After this lesson, you will be able to define and analyze the relationship among the terms constant, variable, dependent variable, and independent variable.

The lesson begins by teaching you that a constant is a value that remains the same, while a variable is a value that changes or varies. It leads you to learn that variables can be dependent or independent. It concludes with examples showing the relationship between dependent and independent variables.

Learn about mathematical terms by helping Wanda the witch, create a golem.

This video includes key concepts, notation, and vocabulary such as the term constant (a value that stays the same and doesn’t change); variable (a value that changes, or varies); independent variable (a variable that can be freely chosen, or does not depend on other variables); and dependent variable (a variable whose value is dependent on the value of an independent variable).

Before watching this video, you should already be familiar with expressions and equations. You should also be familiar with evaluating expressions.

After watching this video, you will be prepared to learn how to solve equations and real world problems involving expressions and equations.
